WebICS 141: Discrete Mathematics I – Fall 2011 5-5 Nested Quantifiers University of Hawaii! Nested quantifiers are quantifiers that occur within the scope of other quantifiers. ! The order of the quantifiers is important, unless all the quantifiers are universal quantifiers or all are existential quantifiers. WebI was wondering how the distribution of the negation works on a nested quantifier, taking into consideration the equivalent formulations. This is what I mean. I have this sentence: ∀ x ( A x → ∃ y ( B x y ∧ ¬ A y)). This is, following the equivalent sentence forms rule ( ∀ x ( P → Q) ≡ ¬ ∃ x ( P ∧ ¬ Q)), equal to

WebDiscrete Mathematics is a term that is often used for those mathematical subjects which are utterly essential to computer science, but which computer scientists needn’t dive too deeply into. But Khan Academy doesn’t cover this in its core mathematics, which culminates in the harder (IMO) calculus subjects, it must be admitted. WebTRANSPOSING QUANTIFIERS Be careful about transposing diﬀerent kinds of quantiﬁers. (∀x)(∃y)[x2 ≤ y] is true. (∃y)(∀x)[x2 ≤ y] is false. However, you can safely transpose two quantiﬁers of the same kind. Coursenotes by Prof. Jonathan L.

However, there also exist more exotic branches of logic which use quantifiers other than these two.

WebThe order of nested quantifiers matters if quantifiers are of different types e.g. ∀ x ∀ y P ( x, y) ≡ ∀ y ∀ x P ( x, y) However ∃ x ∀ y P ( x, y) is not the same as ∀ y ∃ x P ( x, y) Explanation Assume P ( x, y) denote " x loves y … WebLet's look at α := ( ∃ x) P first. As P ( 1) is true, since 1 ∈ A ∧ 1 ∈ Z, there is an x such that P, hence α is true. Now let's consider β := ( ∀ x) P. As P ( 3) is false, since 3 ∉ A, P is not true for all x (if the domain of the quantifiers is restricted to A, take π as example). Hence β is false. (a) α → β is false, as α is true, but β isn't.
